摘要

摘要: 利用岩心、测井及生产测试等资料，在评价天然裂缝特征的基础上，分析了不同类型裂缝的常规测井响应特征，并利用常规测井资料对其进行识别，进而评价不同类型裂缝与气藏动态气水分布之间的关系，并探讨其地质成因。研究表明，新场气田须二段储层主要发育构造裂缝和成岩裂缝2种成因类型。其中，绝大多数构造裂缝为剪切裂缝，按其倾角特征可进一步分为高角度缝、斜交缝和低角度缝；成岩裂缝主要为层理缝，有效性较好，对整体上改善储层物性贡献较大。新场须二段气藏动态气水分布与裂缝发育程度及裂缝类型关系密切，其中以发育低角度裂缝或网状缝为主的储层表现为产水或快速高含水，而以高角度缝发育为主的储层往往为高产气层，且稳产时间相对较长。研究认为，基于该区气藏气水分布的复杂特点，储层中不同类型的天然裂缝造成渗透率的各向异性是影响气藏动态气水分布的关键因素。

Abstract: The characteristics of natural fractures in the second member of Xujiahe Formation in Xinchang gas field were studied using core, logging and production data. The responses of natural fractures of different types were determined using conventional logging data, by which we evaluated the influence of various fracture types on dynamic gas and water distribution, and discussed their geologic origin. Tectonic and diagenetic fractures are predominant in the Xujiahe reservoirs in Xinchang gas field. Most of the tectonic fractures are shear fractures, which can be classified into high angle, oblique and low angle fractures according to their inclination angles. The diagenetic fractures are mainly bedding fractures with a good effectiveness, and contribute greatly to reservoir physical properties. The dynamic gas and water distribution and fracture development in the study area were closely related to the development degree and type of fractures. The reservoirs which mainly develop low angle fractures (especially bedding fractures) or network fractures produce water or meet high water cut rapidly, while reservoirs with high angle fractures show a high and stable gas yield rate. Permeability anisotropy caused by natural fractures of different types controlled the dynamic gas and water distribution in the study area.
